Couple a 3D with a 1D model

Please login with a confirmed email address before reporting spam

Hello,

I would like to calculate the heat conduction in a metal plate, which is cooled with cooling water that flows through a borehole in the plate. The conduction in the plate should be modeled in 3D. For the cooling water only the temperature should be modeled in 1D (in flow direction) using heat transfer coefficients for the heat transfer from the plate to the water. How could this be done ?

Hello Henrik,

If your license includes the Pipe Flow Module, you can follow the approach presented in this model. Without the Pipe Flow Module, you would need to use a component coupling to pass the information between the 2D boundary of the borehole in the 3D model and the 1D midline of the pipe. See also this similar thread.

Best regards,

Jeff
